Methods, Systems, and Computer Program Products for Processing a Nature of Address Indicator and/or Calling Party Number to Support Telecommunication Features

1. A method of processing a call, comprising: performing operations as follows on at least one processor: examining a nature of address indicator in a signaling message associated with a calling party of the call wherein the call is within a jurisdiction having a national nature of address indicator associated with the jurisdiction; allowing the call to complete in a jurisdiction associated with a national nature of address indicator when the nature of address indicator is international; and processing a portion of the digits associated with a calling party number to facilitate operation of a service when the nature of address indicator is national; wherein the signaling message is a signaling system seven initial address message.

2. The method of claim 1 , further comprising: blocking a calling party number in the signaling message from being communicated with the call; and creating a call record.

3. The method of claim 1 , wherein the call originates as a wireless call.

4. The method of claim 1 , further comprising: blocking the calling party number from being communicated with the call when the nature of address indicator is international; and determining whether to block the calling party number to be communicated with the call based on whether the service has been paid for by a customer when the nature of address indicator is national.

5. The method of claim 1 , wherein the service is a push-to-talk service.

6. A system for processing a call, comprising: a processor; and a memory coupled to the processor and comprising computer executable program code that when executed by the processor causes the processor to perform operations comprising: examining a nature of address indicator in a signaling message associated with a calling party of the call wherein the call is within a jurisdiction having a national nature of address indicator associated with the jurisdiction; allowing the call to complete in a jurisdiction associated with a national nature of address indicator when the nature of address indicator is international; and processing a portion of the digits associated with a calling party number to facilitate operation of a service when the nature of address indicator is national; wherein the signaling message is a signaling system seven initial address message.

7. The system of claim 6 , wherein the operations further comprise: blocking a calling party number in the signaling message from being communicated with the call; and creating a call record.

8. The system of claim 6 , wherein the call originates as a wireless call.

9. The system of claim 6 , wherein the operations further comprise: blocking the calling party number from being communicated with the call when the nature of address indicator is international; and determining whether to block the calling party number to be communicated with the call based on whether the service has been paid for by a customer when the nature of address indicator is national.

10. The system of claim 6 , wherein the service is a push-to-talk service.

11. A computer program product for processing a call, comprising: a computer readable medium comprising computer readable program code that when executed by a processor causes the processor to perform operations comprising: examining a nature of address indicator in a signaling message associated with a calling party of the call wherein the call is within a jurisdiction having a national nature of address indicator associated with the jurisdiction; allowing the call to complete in a jurisdiction associated with a national nature of address indicator when the nature of address indicator is international; and processing a portion of the digits associated with a calling party number to facilitate operation of a service when the nature of address indicator is national; wherein the signaling message is a signaling system seven initial address message.

12. The computer program product of claim 11 , wherein the operations further comprise: blocking a calling party number in the signaling message from being communicated with the call; and creating a call record.

13. The computer program product of claim 11 , wherein the call originates as a wireless call.

14. The computer program product of claim 11 , wherein the operations further comprise: blocking the calling party number from being communicated with the call when the nature of address indicator is international; and determining whether to block the calling party number to be communicated with the call based on whether the service has been paid for by a customer when the nature of address indicator is national.

15. The computer program product of claim 11 , wherein the service is a push-to-talk service.
